Effects of interventional vascular embolization at different timing on prognosis and serum S100 calcium-binding protein B level of patients with aneurysmal subarachnoid hemorrhage

Early vascular interventional embolization is beneficial to the alleviation of brain injury and the reduction of serum S100B level.

A total of 229 aSAH patients enrolled from January 2016 to January 2020 were divided into an early-stage group (n=66), a middle-stage group (n=95) and a late-stage group (n=68. Their baseline data, serum indices and clinical outcomes were compared. The factors affecting their prognosis were analysed. The value of serum S100B level for predicting the prognosis was evaluated.

To evaluate the effects of interventional vascular embolization at different timing on the prognosis and serum S100 calcium-binding protein B (S100B) level of patients with aneurysmal subarachnoid hemorrhage (aSAH).

The early-stage group had the highest GOS score, and the late-stage group had the lowest score (P<0.05). Older age, large diameter of aneurysm, high Hunt-Hess grade upon admission, late surgical treatment and high S100B level were risk factors for the poor prognosis of aSAH patients. The optimal cut-off value of S100B for predicting the prognosis was 2.785 [µg/L. The area under the receiver operator characteristic curve, sensitivity, specificity, Youden index and 95% confidence interval were 0.892, 84.3%, 86.3%, 0.706 and 0.844-0.940, respectively.
